If I am single filing on my own, but I got added to the deed and mortgage of my fiance’s Home this year should I include that information on this year’s return?

If you are added to the deed and mortgage of a home, you can claim the portion of mortgage interest and property taxes you actually paid in 2017 as itemized deductions on Schedule A. If you claim your portion, make sure that your fiance does not claim the whole mortgage interest and property taxes, but only his portion.

If you did not pay part of the mortgage and property taxes, then you cannot claim anything on the home.
